问题:

如何显示 blob 数据类型的图像？

我试过:

function getBlob() {
     $data = $this->user_model->getBlob();
     echo "<img src="base64_encode( $data['IMAGE'] )">";
}

但不起作用。

您忘记了 data:URI scheme (data:image/jpeg;base64,) :

Wikipedia:

The data URI scheme is a URI scheme (Uniform Resource Identifier scheme) that provides a way to include data in-line in web pages as if they were external resources [...]

按如下操作:

echo '<img src="data:image/jpeg;base64,'.base64_encode( $data['IMAGE'] ).'"/>'
